This invention relates to inlet ttings for fluid tanks, reservoirs,Swimmingpools and similar fluid containers.

A primary object of the invention is to provide an inlet fitting of thenozzle type in which a member is permanently fixed Within the wall ofthe reservoir or pool and the position of the nozzle is adjustable withrespect to the fixed member.

Another object of the invention is to provide a nozzle fitting in whichthe nozzle may be removed, without mutilating the permanent fluidcontainer wall with the possibility of injuring the water-proofing ofthe wall which renders it impervious to fluids, and replaced by anothernozzle of different form or shape.

These and other objects of th-e invention and the means for theirattainment will be more apparent from the following detailed descriptiontaken in connection with the accompanying drawing illustrating apreferred embodiment thereof, in which Fig. l is a sectional viewthrough a preferred form of the inlet tting as it is kpositioned withinthe wall of the pool or tank.

Fig. 2 is an end view of the inlet fitting set in the wall as it appearsfromlthe inside of the tank or pool. Y .Y

Fig. 3 is a sectional view of a modified form of the invention also setin thewall of the pool or tank.

In nozzle type inlet fittings for tanks, pools and such fluidvcontainers it *has been the practice to make the nozzle of a singlemember and embed it in the wall of the tank or pool and it then becomesa permanent part of the wall and remains fixed therein. Usually thenozzle was permitted to projectV beyond the face of the foundation walla'predetermined distance so that a desired thickness of filling orgrouting could be added tothe face of the wall and the grouting facedwith a finishing tile or brick. Due toinaccuracies in the building ofthe pool or tank wall or inaccuracies in the positioning of the nozzleor if the wall is of concrete, which is the usual material used forbuilding tanks and pools, the concrete forms would warp or be Yinaccurately placed so that when the wall was completed, it was foundusually that the nozzle projected too farbeyond the wall face or not farenough so that the nozzle must necessarily be cut oif in the former caseand in the latter case an extension must be laboriously added or thegrouting or tile or both must be smoothed about the nozzle opening andin that Way form an aperture to the nozzle end in the wall. My inventioncontemplates overcoming these difficulties by making the inlet fittingof two parts, one part being permanently fiXed Within the wall and thenozzle part being a separate member and adjustable with respect to thefixed member and the wall face. Y

The invention shown in its preferred form in Fig. l consists of thesleeve l embedded within the wall 2 and may be 0f bronze or any othermaterial but is preferably made of some rust resisting metal; The sleeveis internally threaded at both ends 3 and 4 forming an elongated chamber5 between the threaded ends. The threaded end?) receives the end of the.pipe P which leads to the fluid supply mains.

' vA flange 1l may be provided upon the sleeve l which is embeddedwithin the Wall 2 so that its outer face is flush with the surface ofthe wall. The purpose o f the ange is to assure a Water-proof joint orbond between the wall and sleeve. This is secured by applying awater-proofing layer l2 over the surface of the wall 2 which overlapsthe face of the flange 1l. Since the water-proofing layer overlaps alarge portion of the face of the flange, a Water-tight bond between thelayer and the flange is secured. It is to be understood that this flangeis not a necessary element of my invention and that my adjustable inlettting will function equally well if the sleeve l is merely a straightsleeve member without the flange.

Although I have shown the sleeve 1 as eX- tending but part way throughthe total wall thickness, it may nevertheless extend all the way throughthe Wall and the reason for constructing it as shown, is to reduce theamount used of the more expensive bronze material Vof which this sleeveis preferably made. The

sleeve Vhowever must be long enough to enable A,

a sufficient adjustment of the nozzle to be made therein. The amount o fadjustment depends upon the inaccuracy with which the sleeve is embeddedwithin the wall and may be considerable in some instances and nil inother instances.

A nozzle 6 which may have any desired degree of taper is externallyscrew threaded at 7 which threads engage the threaded end 4 of thesleeve. This nozzle 6 is screwed into the sleeve 1 so that the large endenters the center chamber 5 of the sleeve and the `smaller end projectsbeyond the sleeve end. The threaded portion 4 of the sleeve is longenough so that the threads 7 of the nozzle 6 will continue to engage thethreads l of the sleeve for a considerable axial adjustment of thenozzle within the sleeve. The chamber 5 is also of sufiicient length sothat the large end of the nozzle may freely move therein for the fulladjustment distance.

After the sleeve 1 is fixed in position in the wall 2 and the nozzleadjusted so that it projects the desired distance from the wall face orthe sleeve end, a water-proofing material 12 of any known type isapplied to the face of the wall and covered with a filling or grouting13 which is then faced with a tile or brick 14:, the outer surface ofwhich is fiush with the end of the nozzle. By making my nozzleadjustable with respect to the face of the wall 2 I am able to apply anydesired thickness of grouting and still have the end of the nozzle flushwith the finished tiled or bricked face.

A plate 8 is lastly fastened to the end of the nozzle by means of a pairof screws 9 which gives the nozzle a finished appearance at the tiled orbricked wall surface 13. It is Vclear however that this plate is not anecessary feature of the invention and may be dispensed with. Itsfunction is to cover the cracks and rough edges necessarily existingwhere the tile 14 is broken away to fit the tile around the end of thenozzle. The sole purpose of the plate is to improve the appearance ofthe inlet opening.

The nozzle 6 may have a groove 15 into which the filling material 13 istamped so that the nozzle is rigidly secured in final adjusted position.This groove, however, is not a necessary part of the nozzle and may bedispensed with if so desired and the nozzle diameter may be made uniformthroughout its length excepting for the threaded portion 7 which mustexceed the diameter of the nozzle body in order to secure the adjustmentof the nozzle in the sleeve.

In the modified form of my invention as shown in Fig. 3 I extend thefluid supply pipe P into the wall 2 and screw thread a coupling 17 onthe end of the pipe. This coupling may be taper threadedat one end 18 toreceive the end of the threaded'pipe P. The other end`19 of the couplingprojects beyond the end of the pipe P and is screw threaded with astraight thread so that it may receive the threads 20 of the nozzle 21and so that its adjustment axially with respect to the pipe and thecoupling may be secured by screwing the nozzle into the coupling. Thenozzle in this modified form projects beyond the face of the wall 2 inthe same manner that the nozzle projects from the sleeve in Fig. 1 andthe nozzle is also adjustable with respect to the face of the wall l2.The grouting and tile is then applied to the wall 2 in the same mannerthat the grouting and tile is applied in the sleeve and nozzleconstruction shown in Fig. 1.

After the nozzle has been fixed inposition and the filling or groutingand tile cemented on the face of wall 2, it may be found that the nozzleis not of the proper proportions and it may be desirable to change it.With my invention this is va very simple operation since it merelyinvolves removing the plate 8, if such a plate has been provided, andchipping narrow apertures into the tile and filling or grouting aboutthe nozzle so as to clear a passage for the nozzle. The nozzle is thenunscrewed from the sleeve and replaced by a nozzle of the properproportions after which the spaces or openings about the nozzle areagain filled in with cement or filling and the plate screwed on the endof the newly inserted nozzle. lVith my inlet fitting, the nozzle may bereplaced without 'injuring or cutting into the water-proofing layer orif a water-proof mixture of concrete has been used the concrete wallneed not be cut into in order to replace or remove the nozzle.

It may be desirable in certain constructions of tanks and pools to havea nozzle which is replaceable at will in which case a permanent aperture22 may be made through thetile and grouting or filling large enough toallow the nozzle to pass freely through the aperture. The end plate v8is large enough to cover this aperture and present a smooth continuouswall just as if the opening were not present and the nozzle were fixedin the sleeve and wall as described above.
